Kirik G. Development of scientific and technical basis for mine energy-efficient compressor machines

Object of study - energy efficient workflows compressor machines and methods for their use in coal mining and coal mine methane, energy use mine water. Purpose - to establish patterns of work processes and to develop methods for the calculation of operating and design parameters of the mine energy efficient compressor machines and methods for their use in the production of coal and methane to increase the efficiency and safety of underground mining. The paper studies the complex method comprising: analysis and synthesis of known positions on the problem; The problem is solved by means of the analysis and synthesis of scientific and technical sources to develop machines for the production of gaseous and liquid nitrogen, laboratory studies on the stands, analytical calculations, the implementation of mine experiments, as well as carrying out physico-chemical studies of coals, protective coatings of parts and assemblies compressor machines . The regularities of changes in the heat transfer coefficient of the heat exchanger shaft compressor system pressure loss; cycle time "injection - Idle" on the volume of the pneumatic shaft, pressure shaft changes the network from its consumption, the emergence of failures different resource units and blocks compressor machines during their operation in the mines and the calculation methods of operating and design parameters of energy-efficient compressor machines and methods their use in the production of coal and methane. Introduced in 1148 energy efficient compressor machines UKVS-7, 5/7; UKVS 10/7; UKVS-15/7 for coal mines; 3 gas recovery installation UKG-5/8 for the extraction and utilization of methane, reducing the risk of methane emissions, the Kyoto Protocol solutions to reduce greenhouse gas emissions; economic effect of reducing methane emissions by 19 million UAH. 9 membrane nitrogen compressor stations AMVP-15 / 0.7 U1 for the prevention and suppression of fires in coal mines with nitrogen gas; actual economic effect of the stations was about 2 billion USD.
